yes, yes, and, yes :-)(just in case - note that "Fit" is different to "Fill" which was suggested by rsatrioadi)

Fit to screen is good for larger images. Or fit to a fixed width and heigth (smaller than the screen)

I would love to be able to manually cycle through the images but suspect that might be impossible(?) - in which case maybe a batch resizer might be the best option (e.g. reduce height to 1050 if larger, reduce width to -say- 1000 if larger. Constrain proportions.) I just had a look at IrfanView - it could do that easy enough.

Another idea I just had:is if an image is larger than xy, then a random section of the image (size xy) would be shown centered on the screen. Sort of like a window into the image.

edit/ adding thumbnail image for last idea (desktop with icons on both sides):

Try Panorama. It has always been and still is my favorite wallpaper changer. Light as a feather, it is approved by Laggy the Snail for use on old slow computers.

Install it, run it, drag & drop a bunch of wallpapers into the program window, then save the list.

You can configure each wallpaper to stretch, tile, or center (doesn't have options for the newer fit or fill)

You can set it to change the wallpaper at intervals from every second to every 24 hours.

You can set it to change them in the order of the list or random order.

You can pause/suspend wallpaper changing from the tray icon.

There are user configurable hotkeys to change the wallpaper. (forward/back)

Panorama doesn't have any resource wasting fancy eye candy on the program's window, or an overabundance of features, but it does have what is important. It was written a long time ago, by Shaun Ivory, who has since gone on to bigger and better things, like working for Microsoft.

Some time within the last year, Shaun took down his site full of freeware which has made getting his software (without bundled crapware from download sites) increasingly difficult. It is essentially abandonware, unsupported, but well written...so unless something drastically changes in Windows itself to cause it to break, it will probably keep on working just as good as it always has for the 14 years that I have used it.

-I couldn't say! My stand has been that if I need the hotkeys, I have not chosen the right wallpapers. ;-) But your question made me first search the AWC forum and then realize that it really has been quite a while since anything happened; I am not too sure the program even is maintained anymore! If he is preparing for version 5 or something entirely else, I cannot know, but I guess it would be best not to make a purchase right now.
